would have done应该不仅仅指虚拟语气吧是否应该还有推测的含义

“would+have+done”虚拟语气，表示对过去事情的假设，意思是“本来会做”。

1. I would have told you all about the boy's story, but you didn't ask me. 我本来会告诉你这个小男孩的故事，但是你没有问我。

2. Without your help, I wouldn't have achieved so much. 没有你的帮助，我是不会取得如此大的成绩。另外，would have done的确也可用于不是虚拟语气的句子：

1. Jordan never would have done that.

乔丹永远不会这么做。

2. Almost everyone would have done it.

几乎大家都会做。

虚拟语气中 would have done should have

1. 虚拟语气的句子按道理是应该配套用的：主句had done +从句would have done。

2. could have done也表示虚拟语气，它的含义是“本来能做但没有做”，如He could have passed the exam.（本来能考及格但是没有）。

3. might have done：①表示对过去某事的推测，认为某一件事情在过去可能发生了。如果使用might，语气就比较婉转或更加不肯定，如：Mary might have learned some Chinese before.

②可以表示过去本来可以做到而实际没有做到的事情，有“劝告”或“责备”的语气，如：You didn't do the work well that day. You might have done it better.

4. should have done只用于谈论过去情况，主要有两个用法：①用于推测过去已经发生的情况。如：He should have arrived by now. 此时他本该到了。②用于指本该发生而实际上未发生的情况。如：You should have told me so before. 你早就应该告诉我
